Ruger Hunting Equipment - Manual (Page 27)

The Ruger M77 Mark II Frontier
Rifle is a compact rifle with a
shorter stock, chambered for
powerful magnum cartridges that
generate heavy recoil. If you are
going to mount a scope on your
Frontier Rifle,
always use the front
scope mounting barrel rib to avoid
injury from the scope during
recoil.
If you are using a scope, you must
use a scope designed with
“intermediate eye relief” of from 7
to 15 inches. Consult your scope
manufacturer for this information.
